BYRON 1B. LAYTON, OF CHICAGO, ILLINOIS CONCRETE SLAB CONSTRUCTION.

Application filed September 2 Be it known that I, BYRON B. LAY'roN, acitizen of the United States, and a resident of the city of Chicago, in.the county of Cook and State of Illinois, have invented certain new anduseful Improvements in Concrete Slab Construction; and I do herebydeclare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawings, and to thenumerals of reference marked thereon, which form a part of thisspecifica- Various constructions have been devised for the purpose ofrapid and efficient assembly of concrete slabs into suitablestructuressuch as silos or other constructions adapted to contain water, as, forinstance, tanks or reservoirs.

This invention relates to a construction wherein a certain type ofconcrete slab is used, together with means for efliciently sealing eachlayer of the slabs and rigidly connecting the same together.

It is an object of this invention to provide a concrete constructionwherein interlocking concrete slabs are used and with a layer ofconcrete formed on the inner or outer side thereof, and embedded inrecesses in said slab to seal the joint between the slabs and lock thesame together.

It is also an object of this invention to provide concrete interlockingslabs provided with recesses in the surfaces adapted to receive bondedtherein a reinforcement of concrete adapted to connect the respectivelayers of slabs together and effectually seal the same at the junctionthereof.

It is also an object of this invention to provide interlocking concreteslabs of relatively great height and narrow width and provided with atransverse recess near the upper and lower ends in the sides thereof,adapted to receive therein a reinforcement of concrete acting to bindadjacent layers of said slabs together in sealing relation.

It is also an object of this invention. to provide a reinforced concreteslab having longitudinal recesses in the abutting vertical edges thereofadapted to receive a filling of cement when in assembled relation, andwith grooves in the surfaces thereof to receive a reinforced concretebank acting to retain adjacent layers together and to seal the jointtherebetween.

It is furthermore an object of this inven- Specification of LettersPatent.

tion to provide interlocking concrete slabs with means associatedtherewith to receive a mold of concrete formed thereon to bind adjacentlayers of slabs together.

It is finally an object of this invention to construct a concrete slabadmitting rapid and secure assembly thereof into a building or the likewhereby additional reinforcing means may be easily formed thereon aftersaid blocks are assembled with one another.

The invention (in a preferred form) is hereinafter more fully describedand defined in the accompanying drawings and specification. I

In the drawings Figure l is a front elevation of a structure composed ofconcrete slabs embodying the principles of my invention. Fig. 2 is afragmentary section taken on line 2-2 of Fig. 1, with parts in ele'ation. Fig. 3 is a section taken on line 5+3 of Fig. 2. Fig. 4 is afront elevation, partly broken away, of a concrete slab showing thearrangement of the reinforcing elements therein.

As shown in the drawings the reference numeral 1., indicates 'astructure such as-a silo or water tank built up of concrete slabs eachindicated as. a whole by the reference numeral 2. Eachof said slabs asconstruct ed, consists of a reinforcing wire mesh 3, suitably associatedwith rods 4:, embedded in the concrete, and said slabs are formed with aV notch 5, in the lower end thereof, and a V projection 6, on the upperend thereof. On the vertical sides, which abut one another when inassembled relation, said slabs are provided with grooves or recesses 7extending. for the whole length thereof. Said slabs are also formed withsurface grooves 8 and 9, respectively, arranged as shown at the upperand lower ends of the slabs and on the inner or outer surface, asdesired, although I have shown the same in assembled relation with saidgrooves on the outer surface thereof.

When the slabs are assembled, as each successive layer is placed inposltion, a suitable mold is set up in position therearound at themeeting faces of 'the respectivev layers and a filling of concretedesignated by the 10, is poured in the mold and allowed to harden afterwhich, of course, the mold is removed. Any suitable peripheralreinforcing elements, such as steel bars 11, are disposed about thevarious points in the formed portion 10, of the concrete, and, as shown,said concrete bonds into the respective grooves 8 and '9, of theassembled slabs.

A filling of cement l2, is poured into the grooved apertures whichextend vertically between adjacent slabs, which, upon hardening, servesto bind the slabs together and effectually seal the meeting .facesthereof. If desired, any coating of cement or other surface finish 13,may be applied, upon the interior of the structure.

A completed structure resembles in appearance a barrel with hoops ofconcrete extending around the same, thus concealing the meeting edges ofthe respective layers 0t concrete slabs, and not only adding greatly tothe appearance of the structure, but also reinforcing the same to alarge extent.

Iain aware that various details of construction may be varied through aWide range without departing from the principles .of this invention. Itherefore do not purextending recesses in the outer surfaces 30 thereof,a unitary encircling band of reinforced concrete molded intosaidrecesses ot the assembled blocks and sealing the horizontal meetingsurfaces of adjacent rows of assembled blocks, and a plastic filling 35poured into said vertical grooves ire said blocks to unite them to eachother vertically, In testimony whereof I have hereunto subscribed myname in the presence of two subscribing Witnesses.
